Show a linked extension's failed build in the app beside the last good one
When a linked extension fails to build under napdock-ext dev, the app now says so and keeps running the last good build.
If you build an extension with napdock-ext dev and a build fails, the error used to appear only in the terminal while the app quietly kept the last good build. Now a toast says “title didn’t build” with the message, and notes that the last good build keeps running. It shows once per failure, not on every re-read.
Settings › Extensions also shows “Last build failed” on the extension’s row until a good build replaces it. Before this change the app showed nothing at all.
